HTML Symbols
HTML Symbol Entities
HTML symbols are not present on standard keyboards, such as mathematical operators, arrow symbols, technical symbols, and shapes.
To add these symbols to an HTML page, you can use HTML entity names.
If no entity name exists, you can use entity numbers.
If a character does not have an entity name, you can use a decimal (or hexadecimal) reference.
| | If you use an HTML entity name or a hexadecimal number, the character will always display correctly. <br>This is independent of the character set used on your page! | | --- | --- |
